PROBLEM TO BE SOLVED: To provide database management technology, capable of unitarily managing databases arranged distributedly over a network. SOLUTION: An integrated object repository server requests the extraction of various information by a query language (e.g., a query language, based on an XML base) to distributed databases connected with a network by using meta-index information owned by the server itself, e.g. the address of a target database, the specific ID of a target person. Information obtained by the inquiry is mapped on the meta-index information stored in an integrated object repository, so that a plurality of pieces of information arranged distributedly in a plurality of databases(DBs) can be unitarily referred to, as though they have been collected to one place.
